 Main power switching connectors (CN R and CN W) (for 230 V class series inverters of
30 HP or above and 460 V ones of 60 HP or above, 575 V ones of 60 HP or above)
The standard FRENIC-HVAC series accepts DC-linked power input. The 230 V class series
inverters of 30 HP or above and 460 V/575V ones of 60 HP or above, however, contain AC-driven
components. To supply AC power to those components, exchange the CN R and CN W connectors
as shown below and connect the AC power line to the auxiliary main power input terminals (R1,
T1).
For the switching instructions, see Figures 5.4-1 to 5.4-4.

Use conditions
By factory default, the CN R is set on the 73X position (230 V class series inverters of 30 to
60 HP, 460V ones of 60 to 125HP and 575V ones of 60 to 150HP) or on the FAN position
(230 V class series inverters of 75 HP or above and 460 V ones of 150 HP or above and
575V ones of 200HP or above), and the CN W is set on the NC position. Do not exchange
them unless you drive the inverter with a DC-linked power supply.
Wrong configuration of these switching connectors causes a heat sink overheat alarm
